The 1966 manual is mostly metric, with the odd thing in Imperial. As such if the charge was 4 grams (4 g), then its mass in grains (gr) would be approximately 62 gr.This is the common manual drawing showing a blatant printing error.
Cartridge should be 47g , 50 gr or 55 gr Ballistite. 4gr would be lucky to clear the barrel ??
There were smoke emission rounds base ignited and Smoke bursting phosphorous rounds which were nose fuzed.
I like the 2" Mortars so always interested in photos and information.
These are all tiny for me. So tiny I can't read anything, which is a shame as they look quite helpful.Here is the section on ammunition from the 1944 Handbook, covering Marks11* to V111*, include yr WP bomb question.

I agree that the photos from Alan1 are too small and I also want to view them.The 1966 manual is mostly metric, with the odd thing in Imperial. As such if the charge was 4 grams (4 g), then its mass in grains (gr) would be approximately 62 gr.
I've come to the conclusion, this after researching and then writing many, many hundreds of technical entries on munitions and weapons for Jane's and other companies, that just because I haven't seen something doesn't mean it did not exist or is incorrect.I agree that the photos from Alan1 are too small and I also want to view them.
There was no 62 gr load for the 2" British mortar as 55gr Ballistite was the largest charge.
I think the manual left the 7 off the 47gr cartridge. All information is welcome. Ron.
